You’ve figured it correctly—it’s the scattering angle.

I tentatively construct a triangle according to the rleg values, and find that the three angles are consistent with the beta values. What does this mean? I searched the Artemis user guild and the mailing list, but could not find the answers. Do you have any ideas?
